Subject: [PATCH v3 0/3] arm64: dts: exynos: gs101: add cpufreq support

Define the CPU clocks and OPPs.

Patch #2 has a dependency on the ACPM clock bindings sent at:
https://lore.kernel.org/linux-samsung-soc/20250903-acpm-clk-v3-1-65ecd42d88c7@linaro.org/

The following error will be seen without the bindings patch:
arch/arm64/boot/dts/exynos/google/gs101.dtsi:10:10: fatal error: dt-bindings/clock/google,gs101-acpm.h: No such file or directory
   10 | #include <dt-bindings/clock/google,gs101-acpm.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Thanks,
ta
